The importance and use of compression garments in sports
Pilař, Lukáš ; Šteffl, Michal (advisor) ; Chrudimský, Jan (referee)
Title: The importance and use of compression garments in sports Objectives: The main aim of this thesis was to analyze the effect of compression garments on performance and recovery in sports. Methods: The work is realized as a review. There were searched three electronic databases: PubMed, Web of Science and Scopus for obtaining possible relevant papers. The same keywords were used to search in all the databases. Results: Based on the study of scientific literature, it was found that compression garments could provide a positive effect only under certain conditions. For speed-strength sports, the compression garments do not improve performance; however, they can reduce pain and fatigue after sports performance. In endurance sports, they can reduce heart rate and help ease the breakdown of lactate after exercise. Conclusion: Compression garments can improve conditions for sports performance, but their impact has not been fully demonstrated yet. Keywords: compression socks, recovery, regeneration, lactate, perceived pain

Říhová, Marcela ; Šteffl, Michal (advisor) ; Krištofič, Jaroslav (referee)
Title: The effect of training exercise on lung functional capacity in gymnasts Objectives: The objectives of this work is to find out the influence of gymnastic exercise on forced vital capacity (FVC), heart rate and blood LA. Methods: Nine female top-level artistic gymnasts participated in the study. The age ranged between 18-25 years. FVC was measured by a personal spirometer, heart rate by a sportester, and blood lactate level by a blood LA analyzer Statistical analysis: Pearson correlation coefficient was used to determine the relationships between variables. The Shapiro-Wilk normality test was used to test normality in our dependent variables. Regression models were used to estimate associations between variables. Non-parametric Friedman test was used to test the differences between measurements and Wilcoxon test was used for post-hoc analysis. Results: A statistically significant increasing (p <0.05) was found in the blood LA as well as in heart rate. A statistically significant relationship (p <0.05) was confirmed between resting LA level and percentage changes in FVC and LA. Keywords: spirometer, sporttester, blood lactate, burpee test, LA, artistic gymnastics

Title: Tennis Injuries and Their Prevention Objectives: To summarize current information about the most frequent injuries of tennis players, their causes and possible prevention on the basis of scholarly and professional literature. Methods: The Bachelor's thesis is carried out as an overview study analysing scholarly and professional literature that deals with the most frequent injuries and their prevention with tennis players. The main goals of work were to search for various professional articles containing the topic of tennis injuries, their appropriate prevention and rehabilitation as well as enlarge the knowledge of these injuries, their causes and possible localization on various parts of body. Another goal was to raise awareness of proper recovery during the performance period as well as appropriate rehabilitation and compensation exercises during the injury. Results: The relevant literature shows that most of the tennis injuries are caused by overload, which means players spend more time than optimum on the tennis court. Another cause of these injuries is an incorrect performance of tennis shot, for which tennis coaches are partly to blame too. Therefore, it is important that the coaches insist on the correct technique from the early childhood of player. Almost all tennis injuries can be...

Pětíková, Nikola ; Šteffl, Michal (advisor) ; Malý, Petr (referee)
Title: Effects of a foam roller during stretching Aims: The main aim of the thesis was to compare effects between the foam roller and stretching exercises. Methods: 10 female students aged 23-24 from UK FTVS participated in this study. All the participants were active athletes. The study was realized as a cross-over trial. There was used tensiomyography using the TMG 100 to measure all the participants. The musculus vastus lateralis were tested in both sides. A generalized linear model was used to evaluate the results. Results: The foam rolling tended to better activate muscle before training and statistically significantly accelerated post-load recovery processes compared to normal stretching. Conclusions: The foam roller could be used effectively after sports performance as a tool to accelerate regeneration, thereby enhancing sports performance.

Suchelová, Nikola ; Šteffl, Michal (advisor) ; Vindušková, Jitka (referee)
Title: Muscle imbalances in pole vault athletes measured by TMG. Goal: The goal of this work was to choose endangered muscle groups and identify possible imbalances by using Tensiomyography machine (TMG 100) and define hypothesis about training pressure of pole vault on growth of muscle imbalances in selected muscle groups. Methods: This work is based on qualitative research. Specifically, six case studies were conducted, during which the importance was placed on discovering characteristic muscle imbalances, which could appear based on training pressure in pole vault. Tensiomyography machine (TMG 100) was used to measure muscle imbalances. Results: Six pole vaulters participated in this study. We found that training and competitive load of pole vault could create muscle asymmetry in muscles deltoideus anterior and trapezius superior. The training may influence also slows down contractions of biceps brachii muscle and another asymmetry on deltoideus anterior between both muscles. We found very low functional symmetry in elbow joint. Key Words: pole vault, athletics, muscle imbalances, TMG
